我已经尝试了两天多的时间来写一个文件到iCloud驱动器.我已经尝试直接编写一个简单的文本文件,然后在本地移动它,使用UIDocumentMenuViewController等.我没有得到任何错误的代码和单步调试,它看起来成功,但当我检查文件是否存在或至少iCloud目录,那里什么都没有.我尝试了模拟器和我的iPhone,触发iCloud同步,以及我能想到的其他一切.

我的主要目标是简单地将文本文件写入iCloud驱动器,后来将成为“数字”文件

我已经设置了我的plist文件和我的权利：

<key>NSUbiquitousContainers</key>
<dict>
    <key>iCloud.com.paul.c.$(PRODUCT_NAME:rfc1034identifier)</key>
    <dict>
        <key>NSUbiquitousContainerIsDocumentScopePublic</key>
        <true/>
        <key>NSUbiquitousContainerName</key>
        <string>myCloudTest</string>
        <key>NSUbiquitousContainerSupportedFolderLevels</key>
        <string>Any</string>
    </dict>
</dict>

我还提到了捆绑版本,如下所述：Save iOS 8 Documents to iCloud Drive

我已经尝试了几十个没有运气的教程.我的最新代码基于此示例：https://medium.com/ios-os-x-development/icloud-drive-documents-1a46b5706fe1

这是我的代码：

@IBAction func ExportFile(sender: AnyObject) {

    var error:NSError?

    let iCloudDocumentsURL = NSFileManager.defaultManager().URLForUbiquityContainerIdentifier(nil)?.URLByAppendingPathComponent("myCloudTest")

    //is iCloud working?
    if  iCloudDocumentsURL != nil {

        //Create the Directory if it doesn't exist
        if (!NSFileManager.defaultManager().fileExistsAtPath(iCloudDocumentsURL!.path!,isDirectory: nil)) {
                //This gets skipped after initial run saying directory exists,but still don't see it on iCloud
                NSFileManager.defaultManager().createDirectoryAtURL(iCloudDocumentsURL!,withIntermediateDirectories: true,attributes: nil,error: nil)
        }
    } else {
        println("iCloud is NOT working!")
        //  return
    }

    if ((error) != nil) {
        println("Error creating iCloud DIR")
    }


    //Set up directorys
    let localDocumentsURL = NSFileManager.defaultManager().URLsForDirectory(NSSearchPathDirectory.DocumentDirectory,inDomains: .UserDomainMask).last as! NSURL

    //Add txt file to my local folder
    let myTextString = NSString(string: "HELLO WORLD")
    let myLocalFile = localDocumentsURL.URLByAppendingPathComponent("myTextFile.txt")
    let written = myTextString.writeToURL(myLocalFile,atomically: true,encoding: NSUTF8StringEncoding,error: &error)

    if ((error) != nil){
        println("Error saving to local DIR")
    }


   //If file exists on iCloud remove it
    var isDir:ObjCBool = false
    if (NSFileManager.defaultManager().fileExistsAtPath(iCloudDocumentsURL!.path!,isDirectory: &isDir)) {
        NSFileManager.defaultManager().removeItemAtURL(iCloudDocumentsURL!,error: &error)
    }

    //copy from my local to iCloud
    if (error == nil && !NSFileManager.defaultManager().copyItemAtURL(localDocumentsURL,toURL: iCloudDocumentsURL!,error: &error)) {
        println(error?.localizedDescription);
    }

感谢您抽出宝贵时间.

干杯,
保罗

我在上面的代码之后在我的iphone上运行了一些代码：

var error:NSError?
    let iCloudDocumentsURL = NSFileManager.defaultManager().URLForUbiquityContainerIdentifier(nil) //?.URLByAppendingPathComponent("myCloudTest")

    var fileManager: NSFileManager = NSFileManager()


    var fileList: NSArray = fileManager.contentsOfDirectoryAtURL(iCloudDocumentsURL!,includingPropertiesForKeys: nil,options: nil,error: &error)!
    var filesStr: NSMutableString = NSMutableString(string: "Files in iCloud folder \n")
    for s in fileList {

        println(s)
    }

它打印出我的文本文件的路径：
file：/// private / var / mobile / Library / Mobile Documents / iCloud~com~paul~c~myApp / MyTextFile.txt

我的文件在那里,我在iCloud驱动器上看不到它.
